Predator and CL could not provide any possible suspects.

Using Code Search for the file, "api-arguments-inl.h" suspecting the below Cl might have caused this issue

Suspect CL: https://chromium.googlesource.com/v8/v8.git/+/bd93135e4ed21ce20268963cfd5db787b2646519%5E%21/src/api-arguments-inl.h

cbruni@ -- Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Thanks!

My changes were too generic to cause this bug, I probably just changed the function singature of FunctionCallbackArguments.

From the msan output (or the lack thereof)  it looks like some internal msan issue (maybe this is n:
	[17655:17680:0519/105041.395907:ERROR:zygote_host_impl_linux.cc(270)] Failed to adjust OOM score of renderer with pid 17687: Permission denied (13)
MemorySanitizer:DEADLYSIGNAL

If not, then the next best candidate is runner::WebAXObjectProxy::MisspellingsCount()

Temporarily assigning over to eugenis@ for the possible MSAN issue, if this is not the case ektar@ might be the next best guess to handle this issue.
